With zero emissions, lower noise and maximum versatility, the power head delivers maximum performance and run time without the hassles of gas and without leaving the 18V LXT battery platform. The lever style lock system allows for quick tool-less installation and replacement of attachments. The 10 in. Pole Saw Attachment provides 7 ft. fixed length for trimming hard to reach branches and the String Trimmer Attachment includes a rapid loading bump and feed trimmer head loaded with 0.080" twisted quiet line.
